Fixed wall shear stress

Andrea_Fen · January 13, 2014, 08:31

Hi,
I'm modeling wind shear stress on a free surface, assuming it as fixed (no VOF) and using a slip condition. How can I assign a fixed shear stress on a boundary? I would also like to define it with a table, to simulate wind variability. Something can be made with a a no-slip condition, but not with slip.

Many Thanks
Andrea

Hi Andrea,

I have a similar problem with Star-ccm. I know that In Fluent one can easily define shear stress for wall.

Have you found a way to solve it in Star-ccm?

Thanks

Hey Farzam,

Did you manage to solve your problem ? can you kindly tell me how we can define shear stress for a wall ?

Thnx
